Liberals and Banks

What I don't get is why do "liberals" "sjws" which Im sometimes called..
Use straight FIAT, US DOLLARS ETC.. instead of crypto..
Wouldnt it be more productive for us to use crypto and take our money out of the banks?
I mean obviously you need cash to buy btc.. but after that, theres tons of ways you can use your btc
and soon to be other cryptos...
I posted on Stupidbook, to see what my "liberal" friends had to say..
their answer.. was it has nothing to do with being liberal;;
or it's not on the top of the list..
but its constant bitching about lobbyist, and politicians..
which the bank funds most of..
Idk, what's some people's thoughts on this.
Im open to all and any opinions
